I wonder whether the 3+ weeks of not running and the hot weather we had evaporated the fuel in the carb and left some deposits / varnish behind that are causing the problem.

I'm going to try running some carb or fuel system cleaner through it and see if that helps or resolves the problem. If not I'll be pulling the carb and tearing it apart.
